1. 1. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Kreshnik Margaritari; [2023]
   Keywords : Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

   Abstract : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

3. 2. A Hierarchical Tucker Solver for the Vlasov-Maxwell System

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Oskar Tegby; [2023]
   Keywords : ;

   Abstract : The Vlasov-Maxwell equations is a common model to describe the behavior of a plasma, but come at the cost of their dimensionality since both spatial and veloocity data is stored in three dimensions. This causes a significant obstacle to be able solve them numerically since the size of the data is N^6, which yields a data size of 8. READ MORE

4. 3. Autoencoder Compression in High Energy Physics

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Sten Åstrand; [2022]
   Keywords : High energy physics; LHC; ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; data compression; Physics and Astronomy;

   Abstract : Situated in Geneva, Switzerland, the Large Hadron Collider is largest particle accelerator in the world, and as such, its operation carries with it some of the greatest technical challenges ever faced. Among them are the huge demands put on data storage capacity by experiments in particle physics, both in terms of rate and volume of data. READ MORE

5. 4. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mantas Petrosius; [2021]
   Keywords : ;

   Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.

6. 5. Analytical Exponential-6 Equation of State Based on Monte Carlo Simulations

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Peter Hallstadius; [2021]
   Keywords : Equation of state; exp-6; Monte Carlo; detonation; shock wave; thermochemical code; Technology and Engineering;

   Abstract : The exponential-6 (exp-6) potential is an intermolecular pair potential that is widely used to model fluids at high densities. The path from molecular interaction to equation of state (EOS) for a gas is not straightforward however. READ MORE
